Python does not do this:

    > help(int)
      class int(object)
      |  int([x]) -> integer
      |  int(x, base=10) -> integer

    > list(map(int, ["1", "2", "3"]))
      [1, 2, 3]

Even if you define a function that takes two parameters, it complains about not having a second one:

    >>> def to_int(a, b):
    ...     return int(a, base=b)
    ...
    >>> list(map(to_int, ["1", "2", "3"]))
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: to_int() missing 1 required positional argument: 'b'

Now replace

  def to_int(a, b):
    ...

with the JS semantic equivalent of

  def to_int(*args):
    ...

because that's how JS function declarations work. You simply have the option to assign names to positional parameters, i.e.

  function fn(a, b) {
    comnsole.log(a, b)
  }

is just syntactic sugar for

  function fn() {
    const a = arguments[0]
    const b = arguments[1]
    console.log(a, b)

}

and that's what people seem to struggle with and argument over for whatever strange reason.
